Cree’s Wolfspeed portfolio adds 650V SiC MOSFETs for broader range of industrial power applications

Cree Inc of Durham, NC, USA has expanded its product portfolio with the release of the Wolfspeed 650V silicon carbide (SiC) MOSFETs (available now in surface-mount and through-hole packages), addressing a wider range of industrial applications.

“Our new 650V MOSFET family is the next step in delivering a high-powered solution to a broader application base, including industrial applications,” says Cengiz Balkas, senior VP & general manager of Wolfspeed. “The 650V MOSFETs deliver power efficiencies that help today’s biggest technology leaders create the next generation of on-board electric vehicle (EV) charging, data centers, and energy-storage solutions to reshape our cloud and renewable energy infrastructures.”

The new 15mΩ and 60mΩ 650V devices, which use Cree’s third-generation C3M MOSFET technology, are claimed to deliver up to 20% lower switching losses than competing SiC MOSFETs and provide the lowest on-state resistances for higher-efficiency and power-dense solutions. End-users benefit from lower total cost of ownership in a variety of applications through the more efficient use of power, reduced cooling requirements, and high reliability.

Compared with silicon, Wolfspeed’s new 650V SiC MOSFETs deliver 75% lower switching losses and a 50% decrease in conduction losses, resulting in a potential 300% increase in power density. Cree says that design engineers can now meet and exceed the industry’s most ambitious efficiency standards, including 80 Plus Titanium requirements for server power.

The new 650V MOSFET family is also suitable for on-board chargers (OBCs) in the EV market. The increased efficiencies and faster switching allow customers to design smaller solutions with added performance, says Cree. Wolfspeed’s 650V silicon carbide MOSFETs also enable bi-directionality in OBCs without compromising the size, weight and complexity of the solution. Furthermore, Wolfspeed’s experience with automotive AEC-Q101 qualification, proven in the E-series MOSFET family, paves the way for future automotive-qualified 650V MOSFETs.

Other industrial applications, such as general-purpose switched-mode power supplies (SMPS), can also take advantage of the benefits of the new 650V SiC MOSFETs from what is said to be the largest, global and vertically integrated supplier of silicon carbide technologies.
